Ametek 2003RP - Table 7-3: Poor Output Voltage Regulation; Table 7-4: Distorted Output; Table 7-5: Unit Shuts down after 3-5 Seconds; Table 7-6: no Output and no Lights on Front Panel

7.3.2 Poor Output Voltage Regulation
If the AC Power Source exhibits poor voltage regulation the following item may be at fault:
Table 7-3: Poor Output Voltage Regulation
CAUSE
SOLUTION
The Remote Sense lines are not
connected at the same point monitored by
the external voltmeter used for load
regulation check.
Connect AC voltmeter to Remote Sense
lines on the Rear Panel Power Output
terminal strip.
7.3.3 Distorted Output
Table 7-4: Distorted Output
CAUSE
SOLUTION
Power source is grossly overloaded.
Reduce load.
Input mains voltage is too low.
Verify at input terminal block that input
voltage is within specified limits.
The crest factor of the load exceeds 3:1.
Reduce load current peaks by reducing
load.
7.3.4 Unit Shuts Down After 3-5 Seconds
Table 7-5: Unit Shuts Down After 3-5 Seconds
CAUSE
SOLUTION
Output shorted.
Remove output short.
Output grossly overloaded.
Remove overload.
Operating load with too high inrush or start
up currents.
Consult factory for application advice.
7.3.5 No Output and No Lights on Front Panel
Table 7-6: No Output and No Lights on Front Panel
CAUSE
SOLUTION
Front panel power switched off.
Switch the breaker on.
No input power to the input connector.
Ensure correct input power.
